2 Claims. (Cl. 339-428) (Granted under Title 35, U. S. Code (1952), see.266) The invention described herein may be manufactured and used by orfor the Government of the United States of America for governmentalpurposes without the payment to me of any royalty thereon.

This invention relates to a battery connector for making electricalconnections to the battery posts of conventional storage batteries.

Many different means have been used for making electrical connections tostorage battery terminals. Where the current to be conducted isrelatively low, various types of clips, as well as driven spikes, havebeen used. A common limitation of such connectors is that in addition totheir current carrying capacity being low they are very prone to workloose under movement and vibration.

The present invention is calculated to overcome these limitations and toprovide a connector having low resistance, reasonably high currentcarrying capacity and the ability to stay in place and maintain goodcontact under adverse conditions of movement and vibration.

In the drawings, Fig. 1 shows the top view of one terminal of theconnector. Fig. 2 shows a side view of the same connector. Fig. 3 showsa section through the connector in position on a battery post. Fig. 4shows a partial section through a modification of the connector shown inFigs. 1, 2 and 3.

More specifically,. is the flat connector body having a terminal openingwith serrated edges 12. Bias spring 14 is welded to or passed through anopening in plate 10. Conductor 16 is attached to body plate 10 by beingsoldered to and compressed between alternate displaced sections 18 or byattachment through screw terminal 20. Flange projections 22 serve toprovide a compressive contact on battery post 24 as opposed to ashearing contact and may be more desirable under some circumstances.

In application, connector plate 10 is forced down over the battery post24 thereby depressing spring 14 against the top of the battery andapplying a bias to 2,865,012 Fatented Dec. 16, 1958 the connector plate.This enables the connector to grip the battery post and form a positivemechanical and electrical connection. Removal is accomplished byrecompressing the spring and tilting the connector plate back out ofcontact with the battery post.

The connector is preferably made of a metal that is reasonably resistantto corrosion by battery acids, or alternatively the connector and springmay be lead coated.

I claim:

1. A battery post connector comprising a substantially flat conductorhaving a serrated edged opening therein consisting of edges that engagethe battery post and which opening is slightly larger than the batterypost adapted to be received therein, coil spring means depending from aposition adjacent said opening and being continuously perpendicular-tothe top of the battery, the base of said coil spring means being fiatand adapted to positively engage the top of the battery case to providea stable support for said connector and also to impart a slight cant tothe connector relative to the horizontal thereby causing the serratededged opening to make a lowresistance electrical engagement with thebattery post.

2. A battery post connector comprising a substantially flat conductorhaving an opening therein of slightly larger diameter than the batterypost and consisting of a plurality of blunt end flanged projectionsangularly disposed within said opening and extending, on a first side ofsaid opening, upwardly away from the top of the battery and on a secondside downwardly toward the battery, coil spring means, designed to cantsaid connector, depending from said first side adjacent said openingcontinuously perpendicular to the top of the battery such that the saidprojections substantially perpendicularly engage the battery post andplace said post in compression, said coil spring means having a baseadapted to positively engage the top of the battery case to provide astable support for the connector, said spring imparting a slight cant tothe connector relative to the horizontal thereby positioning the flangedprojection perpendicularly to the battery post to make a stable lowresistance electrical contact therewith.
